Component Tests

Accessory Drive Belt Tensioner - Static Check

The accessory drive belt tensioner may be checked statically as follows:

1. 1. Inspect the area surrounding the accessory drive belt tensioner for lubricant or

other contamination. Rectify any leaks before installing a new accessory drive belt
tensioner. If the accessory drive belt tensioner is contaminated, do not attempt to
clean it as the damping mechanism inside may be damaged. INSTALL a new
accessory drive belt tensioner as necessary. TEST the system for normal operation.

2. 2. Detach the accessory drive belt in the area of the accessory drive belt tensioner.

3.

NOTE: The accessory drive belt tensioner has a damping feature, which is usually a
friction device, therefore some friction within the system is normal.

3. Using the correct tool, move the accessory drive belt tensioner from its relaxed

position through its full stroke and back to the relaxed position to make sure there
is no excessive stick, grab or bind, and to make sure there is tension on the
accessory drive belt tensioner spring.

4. 4. Rotate the accessory drive belt tensioner pulley and check for damage, freedom of

rotation and alignment. INSTALL a new accessory drive belt tensioner as necessary.
TEST the system for normal operation.

5. 5. If the accessory drive belt tensioner meets the above criteria, proceed to test the

accessory drive belt tensioner dynamically. If the accessory drive belt tensioner
does not meet the above criteria, INSTALL a new accessory drive belt tensioner.
TEST the system for normal operation.

centrally on the flat pulleys. TEST the system for
normal operation.

CHECK the pulleys for excessive end float and

bent flanges.

With the engine running at idle, use a

stethoscope to identify the source of the noise.
INSTALL new components as necessary. TEST the
system for normal operation.

CHECK the extent of the fraying by referring to

the illustrations shown in the Visual Inspection
section. Only INSTALL a new accessory drive belt
if the fraying is within the criteria quoted in the
Visual Inspection section. TEST the system for
normal operation.

CHECK the pulley(s) for damage, freedom of

rotation and alignment. INSTALL new components
as necessary. TEST the system for normal
operation.

*

*

The accessory drive belt tensioner may be checked dynamically as follows:

1. 1. With the engine running, observe the accessory drive belt tensioner movement.

The accessory drive belt tensioner should move (respond) when the engine is
accelerated rapidly or when the A/C clutch cycles ON and OFF (the degree of
movement can be up to 4 mm). If the accessory drive belt tensioner movement is
not constant without engine acceleration or A/C clutch cycling, a pulley or shaft is
possibly bent, out of round, or the damping mechanism inside the accessory drive
belt tensioner may be damaged. INSTALL a new accessory drive belt tensioner as
necessary. TEST the system for normal operation.

2. 2. Excessive accessory drive belt rideout (uneven depth of grooves in the accessory

drive belt) may cause excessive accessory drive belt tensioner movement. Check
the condition by installing a new accessory drive belt. REFER to:
